If your BMW X5 brakes aren't responding the way they used to, don’t take it for granted. It could be due to worn brake pads, low brake fluid, faulty calipers, brake line issues, air in the lines, brake booster problems, or warped brake discs. Take your vehicle to the nearest European service center to diagnose and fix the brake problem for safe driving experience.
